I'd say 1979-07-24 is a pretty good choice, good recording with the band on fire with one of the best setlists they ever played, probably the best TYG ever and a brilliant ALS
Another one would be Montreux 1970 as mentioned before
I want to give the MSG shows in 1973 some praise too, the best Roberts voice was the whole year and good soundboards

Live Aid gets undeserved shit, I mean yeah they shouldn't have played in the state they were in, needed way more rehearsing but what we got isn't that bad, Jimmy's gear is horribly tuned and the audio levels are all over the place but if you actually listen to what he's playing he's doing a pretty good job! Better than some 77 shows

Seattle is one of the shows I just can't listen to because the sound quality is so horrendous, I love the idea of the near 3 hour show as early as 72 but man.... The sound is really rough, to the point that you can barely tell which song you're listening to

He's even better there than he was in pretty much all of '73 and march of '75, if he hadn't caught that damn thing '75 would have probably been the best tour they ever played, even with his voice it's one of my favorite tours
And damn Percy rips the harmonica up
PS. I could have totally seen IMToD be switched with WtLB, like go between them on different nights, would have been really cool

Januari was obviously a rough month with Jimmys finger and Percys flu but man, Wanton Song and WTLB are without a doubt the highlight of those shows, does anybody here know why they were dropped so quickly?

I don't think you can pin it on one year really, I mean the early part of 75 was bad but march and onward is fine I think, parts of 73 and 77 is worse if you ask me, hell late 72 was pretty rough, the worst month of Roberts voice might be January of 1975 though
